SEPARABLE BUTTON,

` 1 i Application led October 18, 1923. Serial No. 669,199.

T0 all whom-t may concern Be it known that I, CARI. E. Sriooc, a citizen of the United States, residing at Cranston, in the county of Providence and State of Rhode Island, have invented certain new und use ful Improvements in tons, ot' which the following is a specification.

My invention relates to buttons of the separable type, and particuiarly to cuii'buttons and other fastening devices.

The essential objects of my invention are facility of manipulation; security against accidental escape; a-nd inexpensiveness of construction.

The invention consists in the means and mechanism for producingthe results above specified substantially7 as hereinafter claimed.

In the accompanying drawings which illustrate the principle oi this invention and constitute a part of this specification.

Figure 1 is a side elevation, partially in vertical central sectioino't a cuff butt-on embodying my invention, showing the parts in locked position,

Figure 2, a'like elevation of the same show ing the parts in position of partial withdrawal, and Figure 3 a transverse section on line 3-31 of Figure 1-.

Like reference numerals indicate like parts throughout the views.

In the construction illustrated the button comprises a master member 5 and a receiving member 6. The latter comprises a head plate 7 with a hollow retracted neck 8 upon whose Haring inner end is a base or end plate 9 having a peripheral flangev 10 engaging the shank by a rolled over bead 11. In this instance a reinforcing plate 18 is frictionally held between the end plate and shank, but this may be omitted or constitute an integral part of the plate 9. The plates 9 and 13 have central holes 15 and 16 respectively.

The master member 5 comprises a head plate 18 having a central perforation 191 a hollow double tapering shank 20 fast thereto; and an end plate or base 22 engaging theinner ared end of the shank by a bead 23, and provided with a central opening 25. Rigidly fixed in this opening by friction, solder, or otherwise intermediate its length is a cylindrical block or plug 27 provided with a central vertical bore 28 and with a centrally transverse or diametrical bore 29 extending to the exterior of the block but of Sep arable But-- A slightly less diameter at its ends to form antion' 19 andl bore 28, having in `this instance' a head portion 34. Near its bottom is an annular groove or recess A helical spring 37 surrounding the rod has its lower end in Contact with the member 27 and its upper end abuttingagainst a shoulder or ring 38 integral with or fixed to the rod. In the bore 29 at opposite sides of the rod 32 are slidably mounted metal balls or spherical members 40 of such diameter that when their adjacent portions are in contact with the member 32 their remote portions project laterally from` the member 27; but when the members 10 are in contact with the rod in the groove 35 they do not laterally project.

To operate the button, the members 5 and 6 are engaged or disengaged with each other by inserting or withdrawing the member 27 into or from the member 6 through the holes 15 and 16. During the instant of insertion or withdra-wal the operator manually depresses the rod 32 whereby the groove 85 is placed in the horizontal plane of the members 40, and the latter are induced inwardly into nonlocking position, as shown in Figure 2. During the locking operation, after the balls have reached a position completely below the plates 9 and 13, and the rod 32 has been released by the operator, the spring elevates the rod and the nongrooved portion of the latter engages the members 40 and causes them to laterally project from the member 27, as shown in Figures 1 and 3. Thus the members 5 and 6 are interlocked.

I claim 1. A separable button formed in two parts, each having a shank, a head, and a base, o-ne base being provided with a central holeq a projecting block fixed on the other base slidable through the hole and provided with a longitudinal bore and a transverse bore, a plunger slidable in the longitudinal bore and provided with a groove normally remote from the transverse bore, and locking members slidably mounted in the second bore normally projecting laterally from the block into the path of the rst base, and registerable in the groove when the plunger is moved and'when the members contact with said lrst base.

2. A separable buttonvformed in two parts, each having a shank, a head, and a base, one

base being provided with a central hole, a block Xed on the second base slidable through the hole, and provided with a diametrioal bore, a plunger yieldingly mounted in the block transversely of the bore provided With ak groove out of alignment With the bore7 and spherical locking members loose in the bore in the path of the first base and adapted to enter the groove When the plunger is depressed.

3. A separable button formed in two parts, each having a shankl a head, and a bese, the base ofone part being provided with a. central hole, and the head of the other part being provided With a central perforation, a

block ixed on the base of the second part slid# able through the hole in the base of the first part and provided with a longitudinal bore and a transverse bore, a plunger slidably mounted in the first bore and ext-ending through the perforation and provided with a groove out of alignment With the second bore, locking members in the second bore normally in Contact with the ungrooved portion of the plunger and projecting into the path of the first base, and a spring engaging the block and the plunger.

In testimony whereof I have afhxed my signature.
